How to Design an Ebook People Actually Finish: A 7-Step Guide (2026)

You've written the thing. Eight pages of advice you know is good, sitting in a Google Doc, and now it needs to look like something worth an email address. That's the moment most ebooks die: not in the writing, in the design. The text gets pasted into a template, the template fights the text, and what goes out is a document that looks like a document.

This guide walks through how to design an ebook that people open, read to the end, and remember who made it. It covers the decisions in order: format, structure, typography, images, cover, and export. It's written for the ebooks most businesses make in 2026, meaning lead magnets, short guides, checklists and playbooks between roughly 6 and 30 pages, not a 300-page novel headed for a Kindle store.

Before you design: what is this ebook for?

The design serves the job, so name the job. A lead magnet needs a strong cover (it's the only thing people see before they sign up), fast skimmability, and a clear next step on the last page. A sales enablement guide needs clean structure and room for data. A paid ebook needs more polish per page because someone is comparing it to the price.

Also decide where it will be read. Nearly every business ebook is read as a PDF on a phone or laptop, not printed. That changes the rules: portrait pages, generous type, high contrast, and no design that depends on a two-page spread.

How to design an ebook in 7 steps

Step 1: Pick the page size

For a PDF ebook, US Letter (8.5 by 11 inches) or A4 (210 by 297 millimeters) is the default and works everywhere. If the ebook is short and punchy, A5 or Half Letter reads beautifully on a phone because each page holds one idea. Avoid landscape unless the content is slides in disguise.

Whatever you pick, set it at the start. Resizing pages after layout is a redesign, not an adjustment.

Step 2: Build the page structure before you style anything

A short ebook needs six kinds of page, and almost nothing else:

1. Cover. Title, subtitle, author or brand, one strong visual.
2. Intro or contents page. What's inside and why it matters, in under 100 words. For anything over 10 pages, add a contents list.
3. Chapter opener. One per section. Big heading, one line of context, lots of space.
4. Body page. The workhorse. Heading, text in one comfortable column, one supporting visual.
5. Feature page. A checklist, a table, a big quote, a worked example. One per chapter breaks the rhythm nicely.
6. Back page. The call to action: book a call, try the product, download the next thing. One action, one button-shaped link.

Map your Google Doc onto those page types before you open a design tool. You'll find out immediately whether the ebook is 8 pages or 14, and which sections are too long for a single page.

Step 3: Set the typography (this is 80% of the design)

Ebooks are read, so type is the design. A few rules that hold up:

Two fonts, maximum. One for headings, one for body. A pairing like a bold geometric sans for headings and a readable humanist sans or serif for body is safe. If you have a brand kit, the fonts are already decided.

Body size 11 to 12 point on Letter or A4, 10 to 11 on A5. Smaller than that on a phone screen sends people to pinch-zoom, and pinch-zoom is where reading stops.

Line length of 45 to 75 characters. That's the range typographers have recommended for a century, as Butterick's Practical Typography explains, and it's why a full-width column of 11-point text on a Letter page feels exhausting: it runs to 100+ characters. Use wider margins or a two-column layout to bring it down.

Line spacing at 1.3 to 1.5 times the font size. Tight leading looks dense; loose leading looks like a draft.

Contrast that passes. Dark grey on white is easier on the eyes than pure black, but keep it dark. The WCAG contrast guideline asks for at least 4.5:1 for body text, and it applies to PDFs as much as web pages.

Hierarchy you can see from arm's length. Chapter titles noticeably bigger than section headings, section headings noticeably bigger than body. If a reader can't tell the levels apart at a glance, the structure from Step 2 is invisible.

Step 4: Add images that carry information

One visual per page is a good target for a lead magnet, and none of them should be decoration. Diagrams that explain a step, screenshots of the process, before-and-after comparisons, charts with one clear takeaway, and pull quotes set large all earn their space. Stock photos of people pointing at laptops do not.

Keep images inside the margins, give them a consistent treatment (same corner radius, same shadow or none, same caption style), and never stretch a photo. If you're generating illustrations with AI, use one style prompt for the whole ebook so the pages look like siblings.

Step 5: Design the cover last

Counterintuitive, but the cover is easier once the inside exists, because you know the ebook's real tone. A lead magnet cover needs three things: a title that states the benefit ("The 10-Minute Weekly Marketing Plan" beats "Marketing Guide"), one visual that hints at the content, and your brand mark. Readable at thumbnail size is the test, since most people first see the cover as a small image on a landing page or in an email.

If you also want a front-and-back cover for a printed version, the booklet guide covers page counts and print margins.

Step 6: Add the pages that make it work as a lead magnet

Three small additions turn a nice PDF into a marketing asset. A short "who this is for" line on the intro page keeps the wrong readers from bouncing and the right ones reading. A footer on every page with your website (people forward PDFs, and the forward is where new leads come from). And a back page with one call to action linked to a real URL, because PDF links are clickable and most ebooks waste that.

Step 7: Export as PDF and test it on a phone

Export as PDF. For a digital ebook, standard quality is fine and keeps the file small enough to email; if it will also be printed, export at 300 dpi. Then open the PDF on a phone before you publish it. Check that the body text is readable without zooming, that links work, that the contents page matches the actual pages, and that the file size is under about 10 MB so it doesn't choke email attachments.
